The San Joaquin County Coroner's Office identified him as 30-year-old Muhammed Rashid of Manteca.

Rashid worked as a part-time security guard and clerk at his family’s Chevron station at Union Road and Yosemite Avenue.

He was last seen Sept. 27 leaving a night guard assignment on Lammers Road in Tracy.

His uncle, Mohammed Ali, told KCRA 3 that Rashid called his wife and mother around 9 p.m. that Saturday to let them know he would be home in about 10 to 15 minutes, but never arrived and hasn’t been heard from since.

Workers at the farm said Rashid had just finished working security at a rodeo there and was traveling on a gravel road on the property, when for an unknown reason, he left the roadway, went down an embankment and into the canal.

A friend of Rashid’s said a similar situation happened a few years ago when another driver died after ending up in the canal.

“It’s dark and there aren’t any lights," Angie Williams said. “There's the canal and the road and there's no fence -- nothing."

Rashid’s body was found Oct. 1 downstream, floating against the water-flow control gates near the South Tracy Boulevard overcrossing.

His Honda Civic also was pulled from the canal.

Ali said the driver-side window was open, and it appeared Rashid tried to get out.

“Because of the cold water, he couldn't survive -- plus, he didn't know how to swim," Ali said.

Due to the body’s decomposition, investigators said an autopsy will be performed to determine whether foul play was involved. A toxicology report will be conducted, as well.

In the meantime, Rashid's family and friends will wait for answers.

"The hardest part is the unknown," Williams said. "Yeah, he's definitely gone, but at the same time, it would be nice to know what exactly did happen and no other families have to go through it again."

Ali said Rashid got married last year, and his wife moved to the United States from Pakistan last month.
